Llyn y Fan Fach — Wales' most mysterious glacial lake, lying quietly in the embrace of the Carmarthen Fans (Bannau Sir Gaer) cliffs in the western reaches of the Brecon Beacons National Park. Formed 11,500 years ago as a cirque lake, its surface is mirror-like and deeply coloured, and it is the birthplace of the Welsh "Lady of the Lake" legend — the story of a young shepherd who met a beautiful fairy emerging from the lake, married her, and their descendants became the famed "Physicians of Myddfai" of the Middle Ages. Starting from Llanddeusant, follow the Afon Sawdde valley gently uphill for 2.6 miles, crest the ridge, and the glacial lake appears unexpectedly at your feet — the semicircular sandstone cliffs reflected in the dark green water, creating a scene of unparalleled wonder. For advanced hikers, traverse the Carmarthen Fans ridge, conquering Fan Brycheiniog (802m), Picws Du, Fan Foel and Waun Lefrith in one go, walking along a knife-edge ridge with sheer cliffs dropping hundreds of metres into the valley below. On the return journey, don't miss the Red Kite Feeding Station — Thursday to Sunday afternoons, over 50 red kites swoop down to compete for food, their nearly two-metre wingspan filling the sky, one of Britain's most spectacular bird of prey experiences.
Follow the valley upstream from Llanddeusant to discover the mysterious glacial lake, challenge the Carmarthen Fans four-peak ridge traverse, and witness the kings of the Welsh sky at the Red Kite Feeding Station
Set off in the morning from the Llyn y Fan car park at Llanddeusant, following the gravel path along the Afon Sawdde valley gently uphill, past a trout hatchery and several mini waterfalls. After 2.6 miles, crest the col — and Llyn y Fan Fach appears unexpectedly at your feet, the semicircular sandstone cliffs reflected in the dark green water, like a scene from a fairy tale. According to legend, this is where the fairy emerged from the lake. For advanced hikers, continue climbing Picws Du (749m), then follow the Carmarthen Fans ridge eastwards, successively conquering Fan Foel, Fan Brycheiniog (802m, the highest peak of the Black Mountain range) and Waun Lefrith — the full circuit is about 9 miles and takes 5-6 hours, the most spectacular ridge hike in South Wales. In the evening, return to Llanddeusant to witness over 50 red kites swooping for food at the feeding station, or head to The Red Lion pub for a pint of local malt ale while listening to the landlord recount the ancient tales of the fairy and the physicians.
A stone-walled old pub built in 1789, now a YHA youth hostel but retaining its 18th-century fireplace and timber beams. The bar is open to the public, serving classic Welsh lamb pies and locally brewed Carmarthenshire Gold ale. Sitting by the fireplace after a day's hiking, listening to the landlord tell the tales of the Lady of the Lake and the Physicians of Myddfai, is the best way to experience Welsh village culture. Average £12-20 per person.
A Victorian-style tearoom in Llangadog village, about a 10-minute drive from Llanddeusant. Signature offerings include hand-baked Welsh fruit bread (Bara Brith) with clotted cream, and Eton Mess made with local strawberries. The tearoom retains its Victorian tiled fireplace and lace curtains, making it the perfect spot for an English afternoon tea after a mountain hike. Average £8-15 per person.
A centuries-old coaching inn in the market town of Llandovery, 10km north of Llanddeusant. The handmade pork pie on the menu uses locally sourced farm pork, with a crispy crust and juicy filling. Paired with Brecon Gold Ale, it is widely regarded as one of the best pub meals in Carmarthenshire. The restaurant also serves Welsh Rarebit and herb-crusted roast lamb chops. Average £15-28 per person.
A boutique restaurant beside Llandovery Castle, specialising in Carmarthenshire local ingredients. The signature Welsh stew (Cawl) uses locally reared lamb slow-cooked for 6 hours with leeks and turnips, served in a traditional wooden bowl. The restaurant also offers herbal teas blended with herbs from the Myddfai area — inspired by the herbal remedies the fairy is said to have taught the Physicians of Myddfai. Average £18-30 per person.
